Quality and Performance:
Lightning Bolt is really opaque and thin.
Barry M 316 (White) is also opaque but very gloopy. (I added thinner)

Beauty UK has a OPI like brush, but is even more gloopy than Barry M.
MUA has a thin brush, and gives a really even application, this shatter seems very shiny and jelly like.
Barry M 311 (Black) is opaque, but is the same as the white in consistency.

Hope this clears up the Shatter/Crackle issue.
ps. many thanks to my mum for letting me use her as a hand model!
